Mechanical Technician

Are you a passionate mechanical technician, that would like to expand the horizons toward a new generation of beam instrumentation for the Future Circular Collider? Then join the team responsible for the mechanical design of beam instrumentation. You'll be part of a thriving community interfacing with scientists for the conception of new instruments, within a collaboration that spans across Europe. You will be guided by experts into the mechanical design of state of the art techniques, interfacing with several services at CERN for the implementation of new Beam Position Monitors, and new techniques for beam emittance measurements. You'll be part as well of the conception and assembly of tests set-up for beam instrumentation alignment, as well as testing prototypes at CERN's beam test facilities like CLEAR.

Your responsibilities

• Mechanical drawings production and reading;
• Assembly mechanical drawings reading;
• Perform mechanical assemblies;
• Experience in product life cycles, quality management and production follow-up.

Your profile

• 1-2 years experience in mechanical drawings production, mechanical assembly and machining (conventional and CNC).
• Experience with beam instrumentation set-ups is a plus.

Skills:

• Mechanical drawings production and reading;
• Assembly mechanical drawings reading;
• Perform mechanical assemblies;
• Experience in product life cycles, quality management and production follow-up;
• Spoken and written English or French, with a commitment to learn the basics of the other language.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Mechanical Engineering (or a related field) and your highest educational qualification is a general secondary education diploma.
• You have never had a CERN fellow or graduate contract before.
• Applicants with a Bachelor's, Master's or PhD degree are not eligible.

Job closing date: at 23:59 CET.

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Working hours: 40 hours per week

Job flexibility: Hybrid

Target start date: 01-February-2026

This position involves:

• Work in Radiation Areas.
• Interventions in underground installations.
• A valid driving licence.
• Exposure to risk of falling from heights during scaffolding assembly and dismantling operations.
• Use of certain mobile work equipment or equipment used for lifting loads (lifting equipment, bridge cranes, aerial work platforms, etc.) requiring a driving authorisation.
• Operations on electrical installations or in their vicinity (over 1000 Volt AC or 1500 Volt DC) requiring a specific authorisation.

Given the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
